Overview
The TESTEC TT-HF-612 is a 500MHz passive oscilloscope probe designed for engineers requiring accurate high-frequency signal measurements. With a 10:1 attenuation ratio and 10 MΩ / 10 pF input impedance, it minimises circuit loading while maintaining signal integrity, making it ideal for RF, digital systems, and power electronics applications.
Part of the TT-HF series, this probe features a rise time of <0.7 ns for capturing fast transients, alongside a 1.3m shielded cable for flexible positioning. Its CAT II 400Vrms and CAT I 500Vrms ratings ensure safe operation in Measurement Category II environments, such as socket outlets, while complying with IEC/EN 61010-031 safety standards. The included LF and HF compensation trimmers allow precise matching to oscilloscope input capacitance, ensuring amplitude accuracy across diverse setups.
Engineers will appreciate the probe’s rugged design, Pollution Degree 2 compatibility, and transient overvoltage protection up to 1500V. For applications requiring readout functionality, the TT-HF-612RA variant adds an integrated attenuator. As a passive solution, it eliminates the need for external power, simplifying deployment in high-speed testing workflows.
